Description
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates in general to improved broadcasting
systems and in particular to an improved tracking system for
locally broadcast electronic works. Still more particularly, the
present invention relates to tracking the distribution of an
electronic work to determine favorable markets for the electronic
work and offer incentives for purchase of the electronic work to
those who received the distribution of the electronic work and
those who distributed the electronic work.
2. Description of the Related Art
Technological advancements in portable computer systems enable
display and audio output of copyrightable works in an electronic
form. These electronic works include, but are not limited to,
music, film, video, and books. The technological advances, for
example, continue to expand the types of electronic devices that
play music and video. Further, technological advances are providing
new ways of encapsulating music and video and new ways of
distributing music and video.
In particular, one of the advances in devices that play electronic
works is in portable electronic devices that play music from MPEG-1
Layer 3 (MP3) and other types of electronic compression file
formats. MP3 files are typically small in memory size and thus are
ideal for storage and play on portable electronic devices. Further,
MP3 and other types of electronic formats of licensed works are
often easily transferable from one device to another via a wire or
wireless network. Further, music files may be streamed from one
portable device to another creating a type of ad-hoc radio
system.
As sharing of electronic works between users proliferates, users
often receive copies of electronic works without the proper
licenses. In some cases, recipients do not intended to acquire
proper licensing. In other cases, however, recipients acquire
copies of electronic works to sample the works and decide if they
would like to purchase the work. Thus, it would be advantageous to
provide recipients of a broadcast copy of an electronic work with
an incentive to purchase proper licensing to the electronic
work.
Further, while persuading consumers to purchase properly licensed
copies of electronic works is an important goal, also important is
selecting markets to promote the author or musician of an
electronic work. When copies of electronic works are downloaded
from a web site, the number of downloads of the electronic work can
be monitored and target markets for promotion of an electronic work
may be determined based on the locations of those downloading the
electronic work. When an electronic work is locally broadcast from
one player to another, however, currently there is no monitoring
tool to determine the target market in which an electronic work is
considered "hot". For example, if one person downloads a new song
and wirelessly broadcasts that song to ten other players that store
a copy of the song who then each wirelessly broadcast that song to
ten other players and so forth, there is currently no method to
monitor that a song has become "hot" in a particular market.
Therefore, it would be advantageous to monitor when an electronic
work is broadcast and track the location of a broadcast, the time
of the broadcast, the recipient's rating of the broadcast
electronic work, the recipient's ratings of others' reviews of the
broadcast electronic work, and other information which is then
accessed by a statistical server when a player is connected to the
Internet. Further, it would be advantageous to monitor the
distribution path of an electronic work so as to compensate users
who essentially promote an electronic work through local broadcasts
of the electronic work to other players and well followed reviews
of the electronic work
It is therefore apparent that there is a need to attach a tracking
mechanism to an electronic work, and in particular a locally
broadcast electronic work, such that recipients of the electronic
work can be tracked, incentives can be offered to the recipients to
purchase the electronic work, incentives can be offered to those
distributing the electronic work, and statistics about local
broadcasts of electronic works may be gathered for promotional
purposes.
SUMMARY OF THE INVENTION
In view of the foregoing, one embodiment of the invention provides

system 100 can read and which is suitable for storing instructions.
In the present embodiment, an example of a non-volatile medium is
mass storage device 118 which as depicted is an internal component
of computer system 100, but will be understood to also be provided
by an external device. Volatile media include dynamic memory such
as RAM 114. Transmission media include coaxial cables, copper wire
or fiber optics, including the wires that comprise bus 122.
Transmission media can also take the form of acoustic or light
waves, such as those generated during radio frequency or infrared
data communications.
Moreover, the present invention may be downloaded as a computer
program product, wherein the program instructions may be
transferred from a remote computer such as a server 140 to
requesting computer system 100 by way of data signals embodied in a
carrier wave or other propagation medium via a network link 134
(e.g. a modem or network connection) to a communications interface
132 coupled to bus 122. Communications interface 132 provides a
two-way data communications coupling to network link 134 that may
be connected, for example, to a local area network (LAN), wide area
network (WAN), or an Internet Service Provider (ISP) that provide
access to network 102. In particular, network link 134 may provide
wired and/or wireless network communications to one or more
networks, such as network 102.
Network 102 may refer to the worldwide collection of networks and
gateways that use a particular protocol, such as Transmission
Control Protocol (TCP) and Internet Protocol (IP), to communicate
with one another. Network 102 uses electrical, electromagnetic, or
optical signals that carry digital data streams. The signals
through the various networks and the signals on network link 134
and through communication interface 132, which carry the digital
data to and from computer system 100, are exemplary forms of
carrier waves transporting the information.
When implemented as a server system, computer system 100 typically
includes multiple communication interfaces accessible via multiple
peripheral component interconnect (PCI) bus bridges connected to an
input/output controller. In this manner, computer system 100 allows
connections to multiple network computers.
Further, multiple peripheral components may be added to computer
system 100, connected to multiple controllers, adapters, and
expansion slots coupled to one of the multiple levels of bus 122.
When implemented as a portable player, for example, a wireless
transceiver 129 may be connectively enabled on bus 122 for
controlling wireless transmissions. Wireless transceiver 129
constantly listens to a pre-programmed public channel for new,
remote parties and sends and receives data and messages on the
public channel. Wireless transceiver 129 may be implemented by any
short-range radio technology, such as, but not limited to,
Bluetooth, 802.11, or Digital Enhanced Cordless Telecommunications
(DECT). An audio output 128 is connectively enabled on bus 122 for
controlling audio output through a speaker, headphones, or other
audio projection device. A display 124 is also connectively enabled
on bus 122 for providing visual, tactile or other graphical
representation formats. A keyboard 126 and cursor control device
130, such as a mouse, trackball, or cursor direction keys, are
connectively enabled on bus 122 as interfaces for user inputs to
computer system 100. In alternate embodiments of the present
invention, additional input and output peripheral components may be
added.
Those of ordinary skill in the art will appreciate that the
hardware depicted in FIG. 1 may vary. Furthermore, those of
ordinary skill in the art will appreciate that the depicted example
is not meant to imply architectural limitations with respect to the
present invention.
The functionality of computer system 100 may be implemented in data
processing systems from servers to portable players. Portable
players may be computer systems that are tailored to efficiently
receive, store and playback electronic works. Examples of portable
players include, but are not limited to, MP3 players, portable DVD
players, electronic book (ebook) play devices, and other devices
specified for playback of a particular type of electronic work.
Portable players may also be incorporated into other types of
portable computer systems, such as wireless telephones and personal
digital assistants.
With reference now to FIG. 2, a block diagram depicts a distributed
network system for facilitating an electronic work licensing,
distribution, and tracking system in accordance with the method,
system, and program of the present invention. Distributed system
200 is a network of computers in which the present invention may be
implemented. Distributed system 200 contains a network 102, which
is the medium used to provide communications links between various
devices and computers connected together within distributed system
200. Network 102 may include permanent connections such as wire or
fiber optics cables, temporary connections made through telephone
connections, and wireless transmission connections.
The client/server environment of distributed system 200 includes
multiple client players 208 and 210 communicatively connected to
network 102. In addition, there are multiple servers, such as
digital DJ server 204 and licensed electronic work distribution
server 206 communicatively connected to network 102.
The client/server environment of distributed system 200 is
implemented within many network architectures. For example, the
architecture of the World Wide Web (the Web) follows a traditional
client/server model environment. The terms "client" and "server"
are used to refer to a computer's general role as a requester of
data (the client) or provider of data (the server). In the Web
environment, web browsers such as Netscape Navigator.TM. typically
reside on client players 208 and 210 and render Web documents
(pages) served by a web server, such as servers 204, 205, and 206.
Additionally, each of client players 208 and 210 and servers 204,
205, and 206 may function as both a "client" and a "server" and may
be implemented utilizing a computer system such as computer system
100 of FIG. 1. Further, the present invention is also implemented
by client players 208 and 210 engaged in peer-to-peer network
communications and downloading via network 102.
The Web may refer to the total set of interlinked hypertext
documents residing on servers all around the world. Network 102,
such as the Internet, provides an infrastructure for transmitting
these hypertext documents between systems connected to network 102.
Documents (pages) on the Web may be written in multiple languages,
such as Hypertext Markup Language (HTML) or Extensible Markup
Language (XML), and identified by Uniform Resource Locators (URLs)
that specify the particular web page server from among servers,
such as server 205, and pathname by which a file can be accessed,
and then transmitted from the particular web page server to an end
user utilizing a protocol such as Hypertext Transfer Protocol
(HTTP) or file-transfer protocol (FTP). Web pages may further
include text, graphic images, movie files, electronic books, sound
files, and streaming audio, as well as Java applets and other small
embedded software programs that execute when the user activates
them by clicking on a link.
While network 102 is described with reference to the Internet,
network 102 may also operate within an intranet or other available
networks, including peer to peer networks. Furthermore, client
players 208 and 210 may connect to network 102 through a data
processing system acting as a port for transferring information
between servers accessible through network 102 and client players
208 and 210. Additionally, preferably, client players 208 and 210
may communicate within a local wireless network, as will be further
described in FIG. 3. This local wireless network is typically
considered "ad-hoc" because it is created when client players 208
and 210 are within wireless broadcast range of one another.
Client players 208 and 210 are computer systems enabled to receive,
play, and store electronic works from one another through local
wireless broadcasts. In particular, the DRM rules attached to an
electronic work received at each of client players 208 and 210 may
control the play and storage of the electronic work. The DRM rules
may require a recipient to first agree to receive a distribution
cookie before client player 208 or 210 can playback or store the
electronic work. The distribution cookie preferably tracks the
distribution of an electronic work and the recipient's responses to
the electronic work. Client players 208 and 210 are required to
update the distribution cookie according to the data values
specified in the DRM rules. Then, when either of client players 208
or 210 connects to network 102, the DRM rules trigger the players
to contact a particular location accessible via network 102, such
that the network location is enabled to access the distribution
cookie. In the example, distribution cookies are accessed by
statistics server 220, however in alternate embodiments, other
locations accessible from network 102 may be triggered to access
distribution cookies.
Further, as described, client players 208 and 210 are portable and
enabled to receive and send wireless transmissions within a local
wireless network range. In alternate embodiments, however, either
of client players 208 and 210 may be considered stationary.
Multiple ranges of wireless transmission capability may be
implemented within a single client player. For example, Bluetooth,
which is a short range wireless technology and 802.11, which is a
mid-range wireless technology, may be implemented within a single
client player to enable multiple ranges of wireless transmissions.
In particular, the DRM rules attached to an electronic work may
specify the preferred reception and transmission ranges for
broadcast of an electronic work and the DRM rules may limit the
type of network available for broadcast of an electronic work. For
example, DRM rules may specify that electronic works are
transmittable by cable only, by Bluetooth only, or by a peer to
peer network allowing a set number of concurrent connections. It is
important to note that while the present invention is described
with emphasis upon wirelessly broadcast electronic works,
electronic works may also be locally broadcast via a cabled network
connection from client player 208 and client player 210. A local
broadcast is one that is accessible to players located within a
particular physical area or network area.
Digital DJ server 204 provides a service for selecting electronic
works for play between client players 208 and 210. Digital DJ
server 204 may track the previous ratings of electronic works made
by recipients at client players 208 and 210. According to one
embodiment, digital DJ 204 may access distribution cookies to track
the previous ratings of electronic works. Further, digital DJ 204
may access the statistical analysis of distribution cookies from
statistics server 220 to determine which electronic work to play
next from the electronic works currently considered "hot" based on
their rates of distribution in a particular area. Then, digital DJ
server 204 may determine which electronic work to play next from
the electronic works that currently reside on client player 208 or
210. Alternatively, digital DJ server 204 may determine which
electronic work to play next from electronic works currently
residing at digital DJ server 204. The functionality of digital DJ
server 204 may also reside within client players 208 and 210.
Licensed electronic work distribution server 206 provides a service
for selling electronic works with licenses in the form of attached
DRM rules. Further, licensed electronic work distribution server
206 provides a service for tracking licenses and use of licensed
electronic works. A user may be required to register an identity or
make a payment to acquire an electronic work and license or just
the license to an already stored electronic work. According to one
embodiment, a user may be provided an incentive to register an
identity with the purchase of an electronic work because the user's
distribution of the electronic work will be tracked and the user
will be given coupons or rebates for subsequent purchases. The type
of coupons and rebates received by the user may be adjusted based
on how many purchases are made by those receiving the broadcast of
the electronic work from the user. Where a user samples an
incomplete version of an electronic work from a wireless broadcast,
the DRM rules may include a link to licensed electronic work
distribution server 206 to acquire a complete version of the
electronic work.
Licenses are preferably attached to electronic works in the form of
DRM rules. These DRM rules may allow a user who has purchased an
electronic work to wirelessly transmit a sample of that electronic
work to other electronic devices. For example, a song purchased by
the user of client player 208 may include DRM rules that allow for
broadcast of the song to client player 210. Additionally, the DRM
rules preferably limit the allowed usage of the sample of
electronic work and are thus transmitted with the broadcast of the
electronic work. Where, however, DRM rules or other licensing rules
are not attached to an electronic work received at client player
208 or 210, the client player may initiate a request for acquiring
licensing to the electronic work with licensed electronic work
distribution server 206 before the electronic work can be
played.
In addition to transferring DRM rules with each electronic work,
other information is transferred. In particular, a distribution
cookie is attached to each electronic work as a tracking mechanism.
Table 1 illustrates examples of the types of entries that may be
included in a distribution cookie. Preferably, the distribution
cookie initially includes the name of the distributor, an
identifier for the purchase, and an identifier for the purchaser of
the electronic work from a licensed distributor. As the electronic
work is broadcast from player to player, each player receives a
copy of the distribution cookie which is then updated with an
identifier for the recipient, the broadcast time, the broadcast
location, any rating responses, and any purchase history. The
location of the recipient may be detected, for example, by a GPS
function of the player or area code of telephone recipient at the
player. Further, the location of the recipient may be detected by
prompting the recipient to enter a zip code location in order to
play the broadcast electronic work at the player.

When client player 208 or 210, having received a broadcast of an
electronic work with a distribution cookie from another player,
connects to network 102, a statistics server 220 preferably gathers
the distribution cookie from the player. Statistics server 220 may
be a single server system that tracks all electronic work
statistics and distributes these statistics. Alternatively, each
distributor may establish a statistics server 220 or other server
location at which distribution cookies are gathered when players
are connected to the network 102 or another network.
As will be further described with reference to FIG. 8, statistics
server 220 preferably includes multiple databases and controllers
enabled to store and analyze information retrieved from
distribution cookies. In addition to gathering the distribution
rates and locations of electronic works, statistics server 220 may
also gather the rating each recipient gave to an electronic work
and the rating each recipient gave to review comments attached to
an electronic work. It will be understood that any response a
recipient of an electronic work has to the electronic work may be
recorded in the distribution cookie for the electronic work.
It is important to note that while distribution cookies are
described as passing from one device to another and passing to
servers, it is understood that a copy of the distribution cookie
file located at one player may be passed to another player or
server. Additionally, it will be understood that while a
traditional cookie is merely a data file readable by a server,
distribution cookies may include a triggering device that initiates
communication with the server when a network connection is
detected. Alternatively, client player 208 or 210 may automatically
trigger communication with a network location specified in a
distribution cookie when a network connection is detected.
As illustrated in Table 2, information gathered from distribution
cookies is organized in a database structure. Table 2 illustrates
an example of information for several of the distribution cookies
returned from the distribution of electronic work "20000001". It
will be understood that alternate types of identifiers may be used
for an electronic work. In the example, two distribution cookies
are logged from region A and one distribution cookie is logged from
region B. The distribution rate logged from each distribution
cookie is based on the number of times the electronic work was
distributed from an initial player to the player returning the
cookie when the player returning the cookie received the electronic
work. It will be understood that other values may be logged to
indicate a distribution rate. For example, the distribution rate
may be broken down into times of day of broadcasts and the type of
network connection used for each broadcast.
Advantageously, based on the distribution rate, statistics server
220 may designate a particular electronic work as "hot" in a
particular region or "cold" in a particular region. For example,
statistics server 220 may assign a hot rating that indicates the
increase in activity for the electronic work in a particular region
based on the information gathered for the distribution cookie. In
the example, the hot rating is a positive or negative number based
on the speed of distribution within a region. In alternate
embodiments, other types of hot rating systems may be implemented
to indicate which electronic works are quickly being distributed in
a particular region. Further, in alternate embodiments, the hot
rating may be based on both the distribution rate and the actual
rating given to the electronic work by each of the recipients.
Additionally, in alternate embodiments, in addition to indicating
whether a particular electronic work is hot or not in a particular
region, it may be determined that the time or point of distribution
was "off" because the work was poorly received at a first time or
point of distribution and later well received by the same
recipients at second time or location. Moreover, while in the
present invention a server system accesses distribution cookies via
network 102 and performs analysis that is then distributed to other
system, in an alternate embodiment, one of client players 208 or
210 may access distribution cookies and perform analysis that is
then used to select the next electronic work to play.

Table 3 depicts an example of analysis of several distribution
cookies designating the identifier for the original player of an
electronic work and the purchases associated with the distribution.
Advantageously, the distribution cookie tracks any purchases made
of the broadcast electronic work. The distribution cookie then
indicates the original purchaser identifier, the new purchaser
identifier, the purchase date, the number of times the work was
distributed before it reached the purchaser, and other important
information about the purchase. Based on this distribution
information, an original purchaser may receive a rebate or other
incentive to reward the original purchaser for distributing the
electronic work to others who then purchased the electronic
work.

Table 4 illustrates an example of analysis of ratings of reviewer
comments made by recipients of a broadcast electronic work.
Preferably, in addition to broadcasting the electronic work,
reviewer comments about the electronic work may be transferred.
Reviewer comments may include comments by independent reviewers
attached at the purchase of the electronic work and comments made
by recipients of the electronic work as it is broadcast from one
player to another. Preferably, recipients of the electronic work
are enabled to view or listen to the reviewer comments and may rate
the comments. Thus, Table 4 shows the combined ratings for a
particular reviewer of a particular work by recipients of the
broadcast of the electronic work. A hot rating for the particular
reviewer may be assigned by statistics server 220 dependent upon
the ratings provided by recipients of the broadcast of the
electronic work. The hot rating represents a reviewer
recommendation depth which equals the number of positive reviews in
a distribution chain over a particular period of time. Licensed
electronic work distribution server 206, for example, may use the
reviewer hot rating to decide to attach review comments by a
reviewer with a good hot rating to new purchases of an electronic
work and decide to detach review comments by a reviewer with a poor
hot rating from new purchases of an electronic work.

In an example of the analysis of distribution cookies and response
to the analysis, first a distributor receives a copy of a new song
with DRM rules allowing full time or temporary wireless broadcast
of the song. The first distributor may optionally review the work,
where the review is added to the distribution cookie for the song
with an identifier for the user. Further, a rating of the first
distributor's previous reviews may be added to the distribution
cookie with the current review of the new song. The first
distributor wirelessly broadcasts the new song to other known top
distributors who subsequently wirelessly broadcast the new song to
others. With each distribution of the song, identifiers for the
sender and the recipient are preferably updated in the distribution
cookie also distributed with the new song. Further, with each
distribution of the song, recipients preferably rate the song and
rate the review written by the first distributor and other
recipients. When distribution cookies are gathered for the new
song, then the markets in which the song was quickly distributed
and highly rated can be determined and returned to the original
supplier. Further, the reviews distributed with the new song that
were the most well received and influential can be determined and
returned to the original supplier. The original supplier may then
distribute payments or electronic coupons to the distributors of
the new song based on the purchases made by recipients due to
trackable responses to a review, quality of review ratings, time to
distribution, bulk quantity of users reached, and other
criteria.
In another example of the analysis of distribution cookies and
response to the analysis, statistics server 220 may monitor the
number of electronic works that a recipient has rated. Recipients
may be given an electronic coupon or other incentive to rate a
certain number of songs. For example, after the recipient of
wirelessly broadcast song rates forty songs, the recipient may be
provided with a limited licensed sample of an electronic work that
is anticipated to meet the preferences of the recipient based on
the prior ratings. Additionally, a playlist of song for that
recipient may be specified by digital DJ server 204 and distributed
to players within broadcast range of the recipient or the
recipient.
Referring now to FIG. 3, there is depicted a block diagram of a
local wireless network broadcast in accordance with the method,
system, and program of the present invention. As illustrated, of
the client players illustrated in FIG. 2, one of these players may
be designated as a primary player, such as primary player 300, for
the local wireless network. Players may vie for the designation as
primary player by offering electronic works or one player may
automatically be designated as primary player. Further, after one
player receives a wireless broadcast of an electronic work, the
player may move to a new broadcast area and become the primary
player for that electronic work in the new broadcast area. It is
important to note that while a wireless network of players is
described, in an alternate embodiment, players may also be
connected via a cable or a wired network connection.
In one example, primary player 300 searches for secondary players
enabled to wirelessly communicate. Primary player 300 is enabled to
wirelessly communicate within a range designated by wireless
broadcast area 302. Once primary player 300 detects other players,
such as secondary players 304 and 306, within wireless broadcast
area 302, primary player 300 may establish a local wireless
network. Within the local wireless network, primary player 300 may
wirelessly stream the electronic work being played on primary
player 300 as a sample electronic work. Preferably, the DRM rules
and context associated with the streamed electronic work are also
broadcast. Additionally, a distribution cookie is preferably
streamed with the electronic work. It is important to note that
primary player 300 is depicted as a sender in the example, however,
in alternate embodiments, primary player 300 may be a recipient
when receiving a wireless broadcast of an electronic work. In
addition, it is important to note that secondary players 304 and
306 are depicted as recipients in the example, however, in
alternate embodiments, secondary players 304 and 306 may be a
senders when broadcasting an electronic work.
An advantage to streaming the electronic work as it is playing on
primary player 300 is that synchronous play is possible on
secondary players 304 and 306. However, in addition to streaming an
electronic work as it plays, the entire sample electronic work may
be wirelessly transmitted as a data file from primary player 300 to
secondary players 304 and 306.
In an alternate example, primary player 300 is constantly
broadcasting a stream within wireless broadcast area 302 of the
current electronic work playing on primary player 300. When
players, such as secondary players 304 and 306 are within the
wireless network area, then the broadcast stream is received at the
secondary players. For example, primary player 300 may be a
stationary player that wirelessly broadcasts within a store or
other defined area to secondary players that enter the store or
other defined area. In another example, primary player 300 may be a
portable player that wirelessly broadcasts from its current
location, thus creating an ad-hoc local wireless network area as it
moves.
The broadcast of an electronic work by primary player 300 may be
controlled by the DRM rules attached to the electronic work being
broadcast. In particular, the DRM rules may specify preferences or
limitations for the reception and transmission ranges and the
transmission mediums. Preferably, wireless and cabled feedback
systems are included in primary player 300 and secondary players
304 and 306 to facilitate range detection.
According to one advantage of the present invention, the DRM rules
may require a recipient of a broadcast to receive a distribution
cookie with the broadcast of the electronic work. The distribution
cookie then tracks information about the distribution of the
electronic work and responses of recipients of the electronic
work.
The context of an electronic work broadcast by primary player 300
may also be transmitted with the electronic work. The context of
the electronic work generally includes the history, reviews, and
distribution path of an electronic work. For example, for a musical
work, the context may include, but is not limited to, a song title,
artist name(s), genre, album name, album type, distributor name,
distributor link, label name, label link, artist link, reviewer
name, reviewer ratings, reviewer text, and the reviewer
recommendation depth. DRM rules may control what portions of the
context of an electronic work may be broadcast.
Secondary players 304 and 306 receive the streamed electronic work
and may synchronously play back the electronic work. Additionally,
secondary players 304 and 306 may store a copy of the broadcast
stream with the DRM rules for later playback. Once secondary
players 304 and 306 move out of broadcast area 302, such as the
position of secondary player 308, then only the stored copy of the
broadcast stream can be played back as allowed by the DRM
rules.
Prior to broadcasting an electronic work, primary player 300 may
query secondary players 304 and 306 for user preferences. Primary
player 300 may then determine which electronic works stored on
primary player 300 should next be played based on the user
preferences from secondary players 304 and 306 and the user
preferences for primary player 300. Alternatively, primary player
300 may transmit all the relevant user preferences to a digital DJ
via an Internet connection and request recommendations for the next
broadcast from the current electronic works accessible from primary
player 300 or any of the secondary players. Further, the digital DJ
may recommend new electronic works and negotiate payment with
primary player 300 for the work from a licensed electronic work
distribution server.
Once a user listens to or views a streamed electronic work at
secondary player 304 or 306, the user preferably rates the
electronic work. A rating may take multiple forms including, but
not limited to, a thumbs up/down, a numeral rating, an alphanumeric
rating, or other selection from a rating system implemented by the
players. Additionally, a user may review the electronic work.
Review comments and the identity of the reviewer may be added to
the context of the electronic work and transmitted among the other
players and broadcast with the electronic work. Advantageously, the
user rating of an electronic work and the user rating of the review
comments may also be updated in a distribution cookie associated
with the electronic work.
If the secondary player, such as secondary player 304, is still
within broadcast range of primary player 300 when the user rates
the streamed electronic work, then secondary player 304 preferably
transmits the rating of the broadcast electronic work to primary
player 300. Primary player 300 may then use the rating to
dynamically adjust the next selected electronic work for
broadcast.
With reference now to FIG. 4, there is illustrated a block diagram
of a music player in accordance with the method, system, and
program of the present invention. As illustrated, player 400
includes an example of components that may operate within an
electronic device enabled to receive, play, and store electronic
works.
First, player 400 includes a wireless transceiver 402 enabled to
send and receive wireless communications. Wireless transceiver 402
may implement multiple types of wireless broadcast technology
including, but not limited to, Bluetooth, 802.11, and DECT.
Next, player 400 includes a playback controller 408 enabled to
synchronize playback of a data stream with the other players
playing the same data stream of an electronic work. As long as
player 400 is within the broadcast range of the primary player,
playback controller 408 may enable playback of a current data
stream of an electronic work or playback of a previously stored
sample electronic work received from the primary player.
Playback controller 408 also preferably condenses and stores data
streams of electronic works in a sample works database 406. Sample
works database 406 includes condensed files, in formats such as
MP3, from streaming electronic works with DRM rules and context.
When player 400 is outside the broadcast range of the primary
player, then the stored sample electronic works in sample works
database 406 may be played back, but only according to DRM rules
for each electronic work. Further, playback controller 408 may
prohibit playback of any electronic work sample acquired without
any licensing rights.
Playback controller 408 also controls playback of electronic works
downloaded onto player 400 with a license for personal use and
potentially also for broadcast to other players. In particular,
electronic works may be downloaded that include a license to
transfer the electronic work file or broadcast the electronic work
to other players as a sample electronic work with DRM rules
limiting playback of the sample work.
When electronic works are streamed from one player to another,
electronic coupons may also be broadcast. Electronic coupons
received at player 400 are stored in electronic coupon database
409. Electronic coupons may include discounts, rebates, and other
incentives for a recipient of a broadcast electronic work to
purchase the electronic work or purchase additional licensing
rights to the electronic work from a licensed electronic work
distribution server. Electronic coupons may be incorporated in a
distribution cookie or may be independent files.
Additionally, when electronic works are streamed from one player to
another, distribution cookies may also be broadcast. Further, when
licensing rights to an electronic work are acquired, a distribution
cookie may be attached to the electronic work. Distribution cookies
received at player 400 are preferably stored in distribution cookie
database 416. When player 400 detects a network connection with a
network enabling access to a statistics server, then recently
updated distribution cookies in distribution cookie database 416
are preferably made accessible to the statistics server and other
specified network locations.
A profile 404 stored on player 400 preferably records the
electronic work preferences for a user. Profile 404 may include,
but is not limited to, a listing of the current electronic works
stored on player 400 and ratings assigned by the user to each of
the electronic works stored on player 400. Additionally, profile
404 may include, but is not limited to, a listing of electronic
works previously listened to or viewed by the user and the rating
assigned by the user to each. Further, profile 404 may include, but
is not limited to, a listing of styles of music, film, books,
musicians, actors, years of recording, and other categories of
preferences for a user. Moreover, profile 404 may include, but is
not limited to, a listing of types of music, film, artists, actors,
songs, and years of recording that a user would like to listen to
or view in the future. Advantageously, a distribution cookie may be
updated with the information stored in profile 404 before the
distribution cookie is transmitted to a statistics server.
Player 400 can transfer the data in profile 404 to other players
within a local wireless network. Further, player 400 may receive
profiles from other players within a local wireless network. A
matching controller 410 within player 400 compares the profiles of
other users within the local wireless network with the context of
the electronic works available for broadcast in licensed works
database 412 and selects music for broadcast to the other players
that best satisfies the preferences of all the listeners. If the
preferences of some users cannot be matched with the preferences of
other users, then matching controller 410 may alternate selections
between those that will satisfy the preferences of a first group of
users and then those that will satisfy the preferences of a second
group of users. Alternatively, if a preference match cannot be made
to the current electronic works, then player 400 may seek to
acquire new electronic works that will match preferences.
As an additional advantage, once other users listen to or view an
electronic work broadcast from player 400, ratings by the recipient
users may be transmitted back to player 400. Matching controller
410 may then dynamically adjust the next electronic work to be
broadcast from player 400 based on the reported rating for the
recently broadcast electronic work.
Further, when a wirelessly broadcast work is received at player
400, a user is prompted to rate the electronic work. The rating is
then stored in profile 404, updated in a distribution cookie, and
transmitted to the player from which the electronic work was
received. Thus, user preferences dynamically change for each
electronic work viewed or listened to by a user.
A purchase controller 414 preferably initiates access via an
Internet or other network connection to a licensed electronic work
distribution server to acquire additional licensing and to register
stored samples of electronic works from broadcasts. A particular
licensed electronic work distribution server may be specified for
purchases in the DRM rules transferred with an electronic work.
In particular, for each rating entered by a user in response to
listening or viewing a work at player 400, purchase controller 414
determines if there is a DRM rule for the electronic work
specifying when a user should be prompted to purchase an electronic
work. If there is a rule requiring prompting upon detection of a
network connection, then purchase controller 414 triggers the
prompting upon detection of a network connection to an electronic
work license server or a licensed electronic work distribution
server. For example, a DRM rule may specify that a user should be
prompted to purchase an electronic work only if the user rates the
work with a thumbs up. In this way, a distributor can distribute a
work, but only prompt purchases from those who have received the
work and given a favorable rating. Further, the DRM rule may
require that those who give a sample work a favorable rating be
required to purchase the additional licensing rights to the work
for further playback.
Referring now to FIG. 5, there is depicted a block diagram of the
wireless communication between a primary player broadcasting music
and the secondary player receiving music in accordance with the
method, system, and program of the present invention. As
illustrated, a primary player 500 includes a matching unit 502 that
selects song 5 from artist 4 with DRM rules, context, and a
distribution cookie, as depicted at reference numeral 504. When
matching unit 502 selects an electronic work, the context data for
the electronic work and DRM rules are matched with a selection of
user preferences from the user of the primary player and the users
of any accessible secondary players. Context data for an electronic
work may include, but is not limited to, song title, artist
name(s), genre, album name, album types (e.g. original LP or
compilation), reviewer name, reviewer ratings, reviewer text,
reviewer recommendation depth. DRM rules may include, for example,
whether the electronic work is free or is ruled by a limited
license.
In this embodiment, the musical work is streamed through wireless
transceiver 506 and received at wireless transceiver 516 of
secondary player 510. Secondary player 510 includes a playback
controller 518 that synchronizes playback of the music stream with
primary player 500 and controls output of the stream through audio
output device 520. The music stream is also stored as sample music
by music playback controller 518 in an electronic work samples
database 512. As illustrated at reference numeral 514, the sample
of song 5, artist 4 with DRM rules is stored in electronic work
samples database 512. Although not depicted, the context is also
stored in electronic work samples database 512 and the distribution
cookies are preferably stored in a distribution cookie database.
While the present invention is described where DRM rules and
context are transmitted in a wireless broadcast of a work, in an
alternate embodiment, only the electronic work is transmitted in a
wireless broadcast of a work.
With reference now to FIG. 6, there is depicted a block diagram of
a sample musical work stored in a secondary player in accordance
with the method, system, and program of the present invention. As
illustrated, the storage of an electronic work, here song 5 from
artist 4, may include work info 604, a music stream file 606, and a
distribution cookie 614.
Work info 604 includes DRM rules 610 and context data 612. DRM
rules 610 preferably control play of the electronic work and output
of the context of the electronic work. Context data 612 preferably
includes historical context, distribution context, and review
context for the electronic work.
In the examples of DRM rules 610, playback of a song stored at a
music player may be allowed when the player is within a certain
transmission range of the primary player. Proximity to the primary
player may be measured by the signal strength detected from the
primary player.
In another example of DRM rules 610, the song stored at a player
may be played back, but only a certain number of seconds of the
song or a lower resolution or downcast in quality may be allowed.
Further, in another example, the entire song may be stored, but the
digital rules may require a decrypt key be accessed from a
licensing database before the song can be played. In particular,
rather than storing the music stream, the music file may be
transferred and stored where the decrypt key is required for later
play. Further, DRM rules 610 may allow playback of the entire
song
In addition to playback of the song, DRM rules 610 may restrict
what portions of context data 612 can be viewed where the context
includes, but is not limited to, song title, album title, composer,
writer, singer, producer, label, year of recording, genre, album
type (e.g. original LP or compilation), reviewer name, reviewer
ratings, reviewer text, reviewer recommendation depth.
Additionally, DRM rules 610 may restrict what review comments the
user can view about the song. Review comments may be included in
the streamed transmission from multiple music reviewers or from
other users who have rated the song. DRM rules 610 may require that
the text or audio review play prior to, during, or after the
electronic work. Advantageously, each user receiving an electronic
work may update context data 612 with ratings and review comments.
Further, when a user specifies ratings and review comments to
update context data 610, the user may further specify DRM rules for
play or display of the rating and review comments.
Additionally, DRM rules 610 may restrict whether a song may be
wirelessly broadcast to other players. In the example, wireless
broadcast is allowed with the restrictions established by the other
DRM rules. Additionally, DRM rules 610 require the recipient of the
wireless broadcast to accept a distribution cookie before playback
of the broadcast electronic work is allowed.
Context data 612 also preferably identifies the manufacturer,
producer, and distributor and provides contact information for
making purchases. Additionally, the music playback controller
preferably adds an identifier for each recipient who receives a
broadcast of an electronic work to context data 612, such that the
distribution flow of an electronic work is tracked. Preferably, a
music playback controller within a music player restricts play of
music or other electronic works and display of context data on the
player according to the DRM rules.
Distribution cookie 614, as described in Tables 1-4, preferably
includes the distribution history of electronic work 602 and
recipient responses to electronic work 602. With each wireless
broadcast of electronic work 602, the distribution history within
distribution cookie 614 may be updated. In addition to the
information described in Table 1, distribution cookie 614 may
include an electronic coupon specified by the distributor and
redeemable according to DRM rules 610.
In an alternate embodiment, the playback controller in a player may
require acquisition of DRM rules for a sample electronic work from
a licensing server prior to playing the electronic work. Further,
where music and other electronic works are received without DRM
rules, the playback controller may automatically initiate requests
for ratings, offers to purchase, and other promptings that might
otherwise be filtered by DRM rules. Furthermore, where a
distribution cookie is not received with an electronic work, the
playback controller may create a distribution cookie based on the
available distribution history and recipient responses.
With reference now to FIG. 7, there is illustrated a block diagram
of the components of a licensed electronic work distribution server
in accordance with the method, system, and program of the present
invention. As illustrated, licensed electronic work distribution
server 206 includes a license controller 702. License controller
702 receives requests to acquire licenses for music. Further,
license controller 702 may receive requests to verify a music
license from players receiving broadcast electronic works.
Preferably, a license database 704 stores licenses for electronic
works and a license registry database 706 stores user identifiers
for those who acquire music licenses. In particular, if the user
meets the requirements of the license, such as paying a fee or
registering, then a license for the electronic work may be
transferred. In an alternate embodiment, licensed electronic work
distribution server 206 controls licenses for all types of
electronic works. As previously described, multiple types of
licenses may be implemented with restrictions on use. The actual
restrictions are preferably defined by DRM rules. When a user
purchases or registers an electronic work, the user may be provided
with a list of available types of licenses. Different costs may be
associated with different types of licenses. Furthermore, it will
be understood that in addition to the example types of licenses
available, other types of licensing agreements may be available and
licensing agreements may be tailored for a particular user.
A purchase controller 708 controls the purchase of licensed
electronic works. As previously described, license controller 702
controls a user purchase of a license for an electronic work
already stored on a player. Alternatively, the user may purchase an
electronic work stored in electronic work database 712 and specify
the type of license preferred for the work. Then, purchase
controller 708 controls the purchase of the electronic work and
license and stores a record of the purchase in purchase database
710.
Advantageously, a prospective purchaser of an electronic work may
be offered an incentive to purchase the electronic work. For
example, the incentive may be in the form of an electronic coupon.
An incentive controller 714 preferably applies incentives to
electronic works and licenses distributed by licensed electronic
work distribution server 206. Incentives may be added as a separate
secure and authenticated file or may be added in the distribution
cookie or DRM rules file. Records of distributed incentives are
stored in incentive database 716. Further, incentive controller 714
preferably controls redemption of incentives received from
purchasers.
Incentives may include conditions for redemption and may adjust in
value depending on recipient responses to an electronic work. Thus,
to redeem an incentive, a distribution cookie may be used to
monitor the distribution history of the electronic work and
responses to the electronic work by recipients. For example, a user
may receive an incentive of a rebate on the purchase of the
electronic work for every purchase of the electronic work by a
recipient of a wireless broadcast of the electronic work from the
user. In another example, each recipient of an electronic work may
receive a discount on purchase of the electronic work in response
to rating the electronic work or writing a review comment about the
electronic work.
A distribution cookie controller 720 preferably attaches a
distribution cookie to each transaction with licensed electronic
work distribution server 206. The distribution cookie may include
distributor information, purchase identification, purchaser
identification, and other relevant information describing the
initial purchase of an electronic work. Further, a distribution
cookie may specify who may access the distribution cookie. In an
example of an advantage of the present invention, an independent
band may distribute electronic works from a web site dedicated to
that band where the distribution cookies attached to the
distributed electronic works are only accessible by the band's
server.
Referring now to FIG. 8, there is depicted a block diagram of a
statistics server in accordance with the method, system, and
program of the present invention. First, distribution cookies
accessed by statistics server 220 are stored in a distribution
cookie database 804. An analysis controller 802 analyzes
distribution cookies in distribution cookie database 804 to
organize data for use in multiple ways including, but not limited
to, determining distribution rates, assigning hot distribution
ratings, tracking the original purchaser of a broadcast electronic
work purchased by a recipient, determining ratings for electronic
works, and determining ratings for reviewers of electronic works.
Examples of analyzed distribution cookies are illustrated in Tables
2-4. The organized data is preferably stored in distribution
statistics database 806.
A statistic recipient database 810 preferably organizes the
intended recipients of distribution cookie information according to
the type of information to be distributed. Businesses, for example,
may subscribe as a recipient of distribution cookie information.
Statistics distribution controller 808 compares entries in
distribution cookie database 804 and distribution statistics
database 806 with the distribution preferences of recipients in
statistic recipient database 810 and controls distribution of
information from databases 804 and 806 to intended recipients.
According to one advantage of statistics server 220, where multiple
users respond to a particular electronic work with positive ratings
or purchases, then ad-hoc networks of users can communicate
preferences for electronic works and force a firestorm of activity
surrounding a particular electronic work. Advantageously, such a
firestorm of activity can then be used by a distributor or promoter
to better target promotion of an electronic work and the artist(s)
of an electronic work.
With reference now to FIGS. 9A-9D, there are depicted illustrative
representations of display choices presented to a user of a player
enabled to receive, store, and broadcast electronic works in
accordance with the method, system, and program of the present
invention. As illustrated in FIG. 9A, responsive to a player
detecting a wireless broadcast, the user is prompted to authorize
reception of a distribution cookie before playback of the
electronic work will be allowed. While in the example the user is
prompted to receive a distribution cookie, in an alternate
embodiment, the user may set a preference to always receive
distribution cookies or to receive distribution cookies for
particular types of electronic works, to receive distribution
cookies from particular broadcasters, and other specifications.
As illustrated in FIG. 9B, the user is prompted to rate the
electronic work. The user may also be prompted to rate overall the
selection of works received from a particular primary player.
Further, the user may be prompted to rate particular
characteristics of a work and to write comments about a particular
work or group of works. The prompting may be displayed while a user
is listening to a synchronous playback of a current broadcast or
when the user is listening to playback of a stored sample from a
broadcast. The rating scale presented to the user may be specified
by the DRM rules, specified by the user, or arbitrarily
selected.
As depicted in FIG. 9C, the user is prompted to select whether to
receive purchase options for the electronic work received from a
wireless broadcast. In particular, when a secondary player receives
a wireless broadcast of an electronic work, the purchasing
information for that electronic work is preferably transferred to
and stored at the secondary player. A user may be automatically
prompted to select whether to initiate a purchase of a licensed
copy of a broadcast electronic work as depicted. Alternatively, a
user may be prompted to only select whether to initiate a purchase
of those broadcast electronic works which the user rates
favorably.
As illustrated in FIG. 9D, the user may alternatively be prompted
to select whether to redeem an electronic coupon to purchase the
electronic work. If a user selects to redeem an electronic coupon
to purchase the electronic work, then a purchase is preferably
initiated with a licensed electronic work distribution server when
the server is accessible via a network.
Referring now to FIG. 10, there is depicted an illustrative diagram
of the distribution of an electronic work in accordance with the
method, system, and program of the present invention. As
illustrated, a licensed electronic work distribution server 206
distributes electronic works via network 1001 with distribution
cookies for tracking the paths of distribution. A path of
distribution may be viewed as a tree with many branches where each
recipient of the electronic work is considered a node. In the
example, distribution server 206 distributes an electronic work to
player 1004. This is the first level of distribution as indicated
by (1). Player 1004 then wirelessly broadcasts the electronic work
to secondary players 1006a-1006n. This is the second level of
distribution as indicated by (1)(2a) and (1)(2n). Each of the
players receiving the wireless broadcast preferably update a
distribution cookie received with the broadcast to indicate the
distribution path. Secondary player 1006a then wirelessly
broadcasts the electronic work to secondary players 1008a-1008n.
This is the third level of distribution as indicated by (1)(2a)(3a)
and (1)(2a)(3n). When secondary player 1008n connects to network
1012, the distribution cookie updated at secondary player 1008n is
accessed by statistics server 220. In particular, the distribution
cookie updated at secondary player 1008n preferably indicates the
path of (1)(2a)(3n). Advantageously, a distribution rate, review
ratings, and other information can be gathered from the
distribution cookie updated along the path.
With reference now to FIG. 11, there is illustrated a high level
logic flowchart of a process and program for controlling a wireless
broadcast of an electronic work from a primary player in accordance
with the method, system, and program of the present invention. As
depicted, the process starts at block 1100 and thereafter proceeds
to block 1102. Block 1102 depicts a determination whether other
devices within the DRM-allowed broadcast range are detected. In
particular, a DRM rule for broadcast of a particular electronic
work preferably specifies the connection types, broadcast ranges,
and other broadcast limitations and preferences. If other devices
are not detected, then the process iterates at block 1102. If other
devices are detected, then the process passes to block 1104.
Block 1104 depicts a determination whether the setting to select
electronic works based on others' preferences is selected. The DRM
rules may require a selection of electronic works based on
preferences. Alternatively, a user at a primary player may require
a selection of electronic works based on preferences. If the
selection based on preferences is not required, then the process
passes to block 1114. Block 1114 depicts selecting a default
electronic work to broadcast. Alternatively, at block 1104, if the
selection based on preferences is required, then the process passes
to block 1106. Block 1106 illustrates transmitting a request for
preferences to the other wireless devices and the process passes to
block 1108. In particular, the request for preferences may specify
which categories of preferences are requested based on DRM rules or
a user specification. For example, the request for preferences may
specify the category of musician preferences and musical style
preferences.
Block 1108 depicts a determination whether preferences from other
wireless devices within broadcast range are received. If no
preferences are received, then the process passes to block 1114. If
preferences are received, then the process passes to block 1110.
Block 1110 depicts selecting the next electronic work to broadcast
based on all the received preferences. In particular, the process
may also require that the electronic work include DRM rules that
allow for wireless broadcasting. Further, the primary player may
offload the electronic work selection process to a digital DJ
located in another electronic device accessible via a network.
Moreover, the playback controller may further filter the sets of
preferences received to only select the next electronic work for
broadcast based on a selection of the preferences received from
secondary players, such as musician preferences. Next, block 1012
depicts broadcasting the sample electronic work with DRM rules
requiring a recipient to receive a distribution cookie for playback
of the electronic work, and the process ends.
Referring now to FIG. 12, there is illustrated a high level logic
flowchart of a process and program for controlling receipt of a
broadcast electronic work at a secondary player in accordance with
the method, system, and program of the present invention. As
illustrated, the process starts at block 1200 and thereafter
proceeds to block 1202. Block 1202 illustrates a determination of
whether a broadcasting wireless device is detected. If a
broadcasting wireless device is not detected, then the process
iterates at block 1202. If a broadcasting wireless device is
detected, then the process passes to block 1204. Block 1204
illustrates a determination whether a request for preferences is
received. If a request for preferences is received, then the
process passes to block 1206. If a request for preferences is not
received, then the process passes to block 1212.
If the process passes to block 1206, a request is presented for the
user to authorize sending preferences. Next, block 1208 depicts a
determination whether the user authorizes sending preferences. If
the user does not authorize sending preferences, then the process
passes to block 1212. If the user does authorize sending
preferences, then the process passes to block 1210. Block 1210
illustrates sending preferences for all applicable users of the
player, and the process passes to block 1212. User preferences may
be set by the device owner, the current user, or a group of
users.
Block 1212 illustrates a determination whether DRM rules for the
broadcast electronic work require accepting a distribution cookie.
If the rules do not require accepting a distribution cookie, then
the process passes to block 1220. If the rules do require accepting
a distribution cookie, then the process passes to block 1214. Block
1214 depicts a determination whether the user accepts the cookie.
The user may set a preference that automatically accepts or rejects
the distribution cookie. Alternatively, the user may set a
preference to be prompted to accept or reject the distribution
cookie. If the user does not accept the distribution cookie, then
the process passes to block 1216. Block 1216 illustrates blocking
playback of the electronic work according to DRM rules when no
cookie is accepted, and the process ends. Alternatively, if the
user does accept the cookie, then the process passes to block 1218.
Block 1218 depicts updating the distribution cookie with new
distribution information for the secondary player and users of the
secondary player. Next, block 1220 illustrating controlling
playback of the electronic work according to DRM rules, and the
process ends.
With reference now to FIG. 13, there is depicted a high level logic
flowchart of a process and program for updating and transmitting a
distribution cookie in accordance with the method, system, and
program of the present invention. As illustrated, the process
starts at block 1300 and thereafter proceeds to block 1301. Block
1301 depicts monitoring the conditions affecting distribution
cookies, and the process passes to block 1302. While each of the
decision processes following are depicted in processing, each one
may be separately monitored and triggered. The decision processes
are only intended to illustrate the types of conditions that may be
monitored that would affect distribution cookies stored on a
player.
Block 1302 depicts a determination whether the user has selected to
purchase the electronic work. If the user does not select to
purchase an electronic work, then the process passes to block 1306.
If the user does select to purchase an electronic work, then the
process passes to block 1304. Block 1304 depicts updating the
distribution cookie for the purchased electronic work with the
purchase information, and the process passes to block 1306.
Block 1306 depicts a determination whether the user selects to rate
the electronic work or a review of the electronic work. If the user
does not select to rate, then the process passes to block 1310. If
the user selects to rate, then the process passes to block 1308.
Block 1308 illustrates updating the distribution cookie for the
rated electronic work with the rating information, and the process
passes to block 1310.
Block 1310 depicts a determination whether the player is connected
to a network through which a statistics server is accessible. If
the player is not connected, then the process passes to block 1314.
If the player is connected, then the process passes to block 1312.
Block 1312 illustrates contacting the statistics server with the
distribution cookie, and the process passes to block 1314. In
particular, a distribution cookie may designate a particular
statistics server to contact or the DRM rules may designate which
statistics servers to contact.
Block 1314 depicts a determination whether the user is wirelessly
broadcasting the electronic work. If the user is not wirelessly
broadcasting the electronic work, then the process ends. If the
user is wirelessly broadcasting the electronic work, then the
process passes to block 1316. Block 1316 illustrates updating the
distribution cookie for the broadcast electronic work with the
broadcast information, and the process ends.
Referring now to FIG. 14, there is depicted a high level logic
flowchart of a process and program for controlling a statistics
server in accordance with the method, system, and program of the
present invention. As illustrated, the process starts at block 1400
and thereafter proceeds to block 1402. Block 1402 depicts a
determination whether a new distribution cookie has been accessed.
If a new distribution cookie has not been accessed, then the
process iterates at block 1402. If a new distribution cookie has
been accessed, then the process passes to block 1404. Block 1404
illustrates storing the distribution cookie in a database. Next,
block 1406 depicts analyzing the distribution cookie for a
distribution rate, purchase history, rating history, and other
settings. Thereafter, block 1408 depicts distributing the analysis
and distribution cookie to subscribers, and the process ends.
While the invention has been particularly shown and described with
reference to a preferred embodiment, it will be understood by those
skilled in the art that various changes in form and detail may be
made therein without departing from the spirit and scope of the
invention.
